TO ALL WHOM 1T MAY CONCERN':

Be it known that I, JAMES Se UPTON, of Battle Creek, inthe county ot' Calhoun,'and in the State of Michi. gan, have invented certain new and 'useful Improvements in Grain-Separator and do hereby declare that the following is a. full, clear, and exact description thereof, reference being-had to the accompanying drawings, and to the letters of reference marked thereon. A i

In the annexed drawings, making part of this specication, A represents the frame of the machine. 'Near one end of thisiframe, and placed crosswise of it in a suitable concave box, is a threshing-cylinder, B. Both the concave and the eylinder'are provided with suitable teeth foithreshing gra-in. D D D represent a series of sieves or perforated boards, ywhich are hung inthe frame at their roar ends, by means .of the straps a a. Their forward ends are connected to crank-shafts e e.- When these crankshafts are revolved, the sieveshavc a rotary reciprocating motion communicated to them. The outeren'ds'o theshafts e'e, on one side of the frame,

'are provided with the lpulleys I I, by means of which motion is given to said shafts. C represents a trough, which forms the bottom to the .frame A,A or rather to the grain-,box of said frame. -Thistrough is inclinedslightly toward the rear-.of theixna'chine, and has an endwisc vibratory motion communicated toit by a rod, G, which connects to a crank-shafttg, on the end of which is a pulley, J.

The trough C empties its grain into a box, E, at'the rear of thev machine. The'grain, however, in falling from1the trough to the box, is subjected to a' blast of air Ifrom a fan,-F,'silt\1ated immediately under the rear end of the trough C. The fan is driven by means ot' a band, which passes around a. pulley on the end of the threshing-cylinder shaft, and thenaroundone on the end of the fan-shaft. .i v'

The grain is fed in to cylinder B in the straw, and, being; threshed from the straw by said cylinder, falla into the trough C, nnd isczxrriedr back and emptied into box' E. The strinvf'ttlls upoirfthe' screen-1),.and is'v carried byy its" lmotion lbackto screen'D, and then to D, in like mann-er. T he meshes of the screens arefrom one'to two inches in diameter, and all grain .which may have lodged in the straw is separated from it by the vibratory motion of the screens, and falls through into the trough C, and is carried backinto. box E.

'The fan F removes all chai from the gra-in as it is falling from thetrough to thcibox.4

1. The screens D D D, combined with the cylinderB, and operating inthe manner set forth for sepas4 rating the grain from the stra\v, substantially as specified.

2. The vibrating-spout 0, in combination with a threshing-cylinder, and the series of screens D D D. when used vsubstantially as and for the purpose set forth. i

In testimony that I claim the foregoing, I have hereuntol set -my hand, this 9th day of 186- JAMES S. UPTON'. Witnesses:
